Rooms are different. Your rent should reflect that.
Square footage is the biggest factor. A 200 sqft room shouldn't cost the same as 120 sqft.
Private bath, parking spot, balcony, walk-in closet, A/C — each adds measurable value.
Rate natural light, noise level, and storage space from 1-10. The algorithm weighs it all.
See exactly why each person pays what they pay — with charts, scores, and shareable results.

Download on the App StoreEach room gets a score based on square footage, binary features (private bath, parking, balcony, etc.), and quality ratings for natural light, noise level, and storage. The total rent is then split proportionally to each room's score — a room with 30% of the total score pays 30% of the rent.
Yes. The core calculator, visual breakdown, sharing, and communal space splitting are all free with no limits. Optional one-time purchases ($1.99 each) unlock PDF export and the ability to save multiple configurations — but you never need them to get a fair split.
The whole point is transparency. Every roommate can see exactly how each room was scored and why the numbers came out the way they did. You can adjust weights, re-rate quality scores, and re-run the calculation until everyone agrees the inputs are fair.
Split Fair works for 2 to 10+ rooms. Whether you're in a 2-bedroom apartment or a large shared house, just add each room and the algorithm handles the rest.
